Have you ever seen the FPSC source code?
You do know Lee and Mike get together and say,"I wonder what happens when we add this line?We can post this as the next RC."

Trigger zones,along with the aforementioned random acts of God,can slow down your level as well.
There are a
lot of threads on the subject of FPSC and speed issues.
I am sure that if you search the forums you will find a lot of information on the subject.
